[U-Boot] [PATCH 2/2] mx6sabresd: Add Serial Download Protocol support

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam at nxp.com>

Add Serial Download Protocol support (SDP), which allows loading
SPL and u-boot.img via imx_usb_loader tool as explained in
doc/README.sdp.

Signed-off-by: Fabio Estevam <fabio.estevam at nxp.com>

In order to get SDP functional on sabresd we need these
two patches from Stefan:

imx: add macro to detect whether USB has been initialized
imx_common: detect USB serial downloader reliably
